I think this brings up another good point. Put your rules in order. Anyone reading them will find the first rule that seems to apply and stop reading. If something is most important, put it first. There will always be conflicts (speed of app vs speed of development), and it is important to put them in the order which you want them to supercede each other. This is not supposed to be a mystery novel, building suspense. Even then, there will sometimes still be times where you can't follow the rules - what then? Obviously, a senior developer (or just a prick like me) will ignore rules that don't apply in a specific circumstance (perhaps you have something running during mouse movement - it obviously has to be fast, or the whole system will die, even at the expense of readability of code). Perhaps a guideline on how to determine you're in a special case, but, more importantly, what to do with that special case. Perhaps a comment block to highlight the non-standard code, why, and what it really does in plain English rather than the mess of code it may really be?

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
